du/Sie

Germany still very much maintains it's formal / informal du/Sie usage. I agree with you that the begining lessons should emphasize the formal Sie. A question such as WIE HEISE DU? does not make much sense, due to the fact that that one would not ask a friend what their name is!

From my experience, I would say you should definitely learn the du form as well, while after you've been introduced to someone; they considerate an insult if you don't use the du form. It's not like in America where using Sir or Maam is always considered respectful and polite. Plus, I think learning the Sie form is quite easy because most things like verbs and what not, stay infinitive and the du form usally needs to be conjugated or declined. With your family and friends you would say "Wie geht's dir?", not "Wie geht es Ihnen?". Hope that helped. If you need any more tips, I'd be glad to help. I've only lived in Germany for 20 months, but I came here knowing nothing and have learned quite a lot of culture since I've been here. It used to be very discouraging having no clue and not being able to communicate or converse. Rocket German definitely helped to launch me into the world that is Deutschland.

Ps. "Wie heißt du wieder?", may come in handy after you've already met someone; but also in that case "Wie heißen Sie?" may not be so offensive, if it's shortly after you've already met someone.
